Equipment Characteristics
Automatic opening and arc length control system for TIG and Plasma welding processes
The AVC is a device that controls the arc length automatically. Its use is essential when looking for automated applications, with high performance and speed in the TIG and Plasma processes, since the variation in the electrode-piece distance in these processes significantly modifies the characteristics of the arc, possibly compromising the welding result. The equipment also makes it possible to automatically open the arc in the TIG process, allowing the application of this process in a robotic production line.
- The AVC has great adaptability in different applications, and the dynamic correction of the arc length can be easily configured according to the use.
- The equipment can be used with pulsed current, alternating current, and also in other special applications.
Automation
The AVC can function as a central component of the automation system, integrating and controlling the operation of the different devices.
System ActuatorThe mechanical assembly that moves the welding torch is made of high strength aluminum alloy, and the main components such as guides and ball screw |
Control unitThe electronic design was specially designed for automated welding operations, so the system has a total of 20 communication ports (analog and digital), allowing great capacity for integration with welding sources, sensors, robots, handling devices, PLCs. |
MicrocontrollerThe micro-processor control unit uses the powerful ARM A7 processor and has a man-machine interface with LCD display for parameter configuration. |
